Harness The Sun's Power With Solar PV Panels
Photovoltaic panels (PV) are the modern standard for sustainable living. By converting sunlight directly into electricity, you can power your home, charge your EV, and heat your water for free. PV panels explained simply: they use semiconductor cells to convert sunlight into usable electricity — no moving parts, no noise. Plus, through the Micro-generation Support Scheme, you can get paid for every unit of unused electricity you export back to the grid.
Whether you're looking at the cost of PV panels for a new build or a retrofit, LVP Renewables can help you find the right solution. With SEAI grant for PV panels available, now is the best time to invest in solar PV panels in Ireland.

PV Panel Output & Solar Calculator
Understand your potential solar PV panel output and calculate your savings.
Calculating PV Panel Output
PV panel output is measured in kilowatt-hours (kWh) and depends on panel wattage, orientation, tilt angle, and local weather conditions. In Ireland, a south-facing 1 kWp system typically produces 850–1,000 kWh per year. The best angle for PV panels in Ireland is between 30° and 35° facing south for maximum energy harvest.
PV panel output per m² averages around 150–200 watts under standard test conditions. The solar PV panel output of modern high-efficiency panels from brands like Longi PV panels and Mitsubishi PV panels can exceed 210W per m². Calculating PV panel output accurately requires considering shading, roof orientation, and local irradiance levels.
Our PV panel calculator tool helps you estimate your system size, expected output, and savings. A solar PV panel calculator takes into account your roof area, electricity consumption, and local conditions to give you an accurate projection. Contact us for a free PV panel simulation tailored to your property.
Output Guide by System Size
- 3 kW System (8 panels): ~2,600 kWh/year — covers ~50% of average home usage
- 5 kW System (12 panels): ~4,300 kWh/year — covers ~80% of average home usage
- 10 kW System (24 panels): ~8,500 kWh/year — ideal for larger homes or small businesses
- Annual Savings: Up to €1,500+ depending on system size and usage patterns
PV Panels vs Solar Panels & Panel Types
Understand the differences and discover which type of PV panel is right for you.
PV Panels vs Solar Panels — What's the Difference?
People often ask about PV panels vs solar panels. In reality, PV (photovoltaic) panels are a type of solar panel specifically designed to generate electricity. Solar thermal panels, on the other hand, heat water directly. When people refer to "solar PV panels", they mean panels that convert sunlight into electricity.
At LVP Renewables, we supply the best solar PV panels in Ireland from leading manufacturers including Longi PV panels and Mitsubishi PV panels. These premium brands offer excellent durability, high efficiency, and strong performance even in Ireland's variable climate.
Balcony & Wall-Mounted PV Panels
Balcony PV panels are an increasingly popular option for apartment dwellers and those with limited roof space. These compact plug-in systems can be mounted on balcony railings or walls to generate electricity directly.
Wall-mounted PV panels provide a versatile alternative when roof installation isn't feasible. They can be fitted to south-facing walls for optimum energy generation. While the output is typically lower than roof-mounted systems due to the angle, they still provide valuable electricity generation and cost savings.
PV Panels with Battery Storage
Combining PV panels with battery storage maximises your energy independence. A battery for PV panels stores excess electricity generated during the day so you can use it in the evening when the sun goes down. This means higher self-consumption and lower bills.
PV panels and battery storage systems are now more affordable than ever. A typical 5 kWh battery costs between €3,000 and €5,000, and when paired with a PV system, it can significantly increase your savings. You can also use your stored energy as backup power during outages.
Interested in using PV panels to heat water? By connecting your PV system to an immersion diverter, excess solar electricity can automatically heat your hot water cylinder — giving you free hot water during sunny periods. This is one of the most cost-effective ways to utilise your solar PV panel output.
Learn About Battery StorageBenefits of Battery Storage
- Store excess solar energy for evening and nighttime use
- Increase self-consumption from 30% to over 70%
- Backup power during electricity outages
- Use PV panels to heat water via an immersion diverter
- Faster PV panel payback period with maximised savings
